Infusion container with multiple chambers

The present invention has an object to provide an infusion container with multiple chambers, where the peel strength of the boundary portion between one and another of multiple medicament chambers is stabilized irrespective of the construction material and structure of the film. The present invention provides an infusion container with multiple chambers, which is formed from a thermoplastic resin film and has a plurality of medicament chambers and for housing medicaments, wherein the medicaments chambers and are liquid-tightly sealed by a peelable weak seal part , the weak seal part is formed to have a plurality of melt-bonding parts different in the melt-bonding strength, the strong melt-bonding part having a largest melt-bonding strength among these melt-bonding parts is dispersed and distributed in the weak seal part , and the total occupied area of the strong melt-bonding part is less than 25% of the area of the weak seal part
